Summary
IBM Langflow OSS versions 1.0.0 through 1.9.6 contain a missing authentication vulnerability in /api/v1/build_public_tmp/ endpoints, allowing an unauthenticated attacker to read build event data or cancel jobs using a valid job identifier, resulting in information disclosure and denial of service.
Risk Assessment
The risk for the organization includes potential exposure of sensitive build-related data and the ability to disrupt system operations by canceling jobs, which may impact business continuity.
Recommendation
It is recommended to immediately upgrade IBM Langflow OSS to version 1.9.7 or later, which fixes this vulnerability, and to enforce authentication for all API endpoints.
Other vulnerabilities in IBM Langflow OSS
See all- CVE-2026-93680Critical
IBM Langflow OSS versions 1.0.0 through 1.12.8 contain an improper authentication flaw that could allow a remote attacker to bypass security restrictions.
- CVE-2026-110186Critical
IBM Langflow OSS 1.0.0 through 1.12.8 could allow a remote attacker to execute arbitrary code due to improper control of code generation.
- CVE-2026-107329Critical
IBM Langflow OSS 1.0.0 through 1.12.4 could allow a remote authenticated attacker to execute arbitrary code due to improper control of code generation.
- CVE-2026-107328Critical
IBM Langflow OSS 1.0.0 through 1.12.4 could allow a remote authenticated attacker to execute arbitrary code due to improper neutralization of code in eval/exec.
- CVE-2026-107327Critical
IBM Langflow OSS versions 1.0.0 through 1.12.4 could allow a remote authenticated attacker to execute arbitrary code due to missing authorization.
- CVE-2026-104339Critical
IBM Langflow OSS versions 1.0.0 through 1.12.3 could allow a remote attacker to execute arbitrary code due to improper neutralization of special elements used in an OS command.
- CVE-2026-12944Critical
IBM Langflow OSS 1.0.0 through 1.10.0 allows attackers to execute arbitrary Python code with root privileges (UID=0) on the Langflow server by submitting components containing socket or urllib imports. This enables AWS credential theft via IMDSv1 SSRF, arbitrary file exfiltration from the container filesystem, and lateral movement to internal services (PostgreSQL, Redis) within the Docker network. The scanner incorrectly returns "validated": true, providing a false security signal.
- CVE-2026-81204Critical
IBM Langflow OSS versions 1.0.0 through 1.11.5 allow a remote attacker to execute arbitrary code due to code injection during graph construction.
- CVE-2026-79724Critical
IBM Langflow OSS versions 1.0.0 through 1.11.5 allow a remote attacker to execute arbitrary OS commands due to improper neutralization of special elements used in an OS command.
- CVE-2026-85025Critical
IBM Langflow OSS versions 1.0.0 through 1.11.5 allow an unauthenticated attacker to execute arbitrary code and access or modify chat sessions through publicly shared MCP project endpoints due to improper enforcement of public-flow security restrictions and session isolation controls.
